Special Considerations in Anesthesia for Laryngeal Cancer Surgery .. Supraglottic laryngectomy offers the advantage of cure with preservation of speech for. Therefore tracheotomy was standard part of laryngectomy (usually under local anesthesia) to establish airway with general anesthesia. The anaesthetic considerations for head and neck cancer surgery are . this is physically impossible (e.g. the post-laryngectomy patient) or because oral.

The anaesthetist will usually have information about the lesion e. Anticipated complications include bleeding, tube obstruction and accidental decannulation.
Trans-nasal high-flow rapid insufflation ventilatory exchange combines apnoeic oxygenation, continuous positive airway pressure and flow-dependent deadspace flushing and has the potential to change the nature of difficult intubations laryngectkmy a hurried stop—start process to a more controlled event, with an extended apnoeic window and reduced iatrogenic trauma.
Comorbidity and pre-operative assessment are considered elsewhere in the guidelines.
Anaesthesia for total laryngectomy.
These programmes have been shown to improve outcomes in patients undergoing major colorectal and gynaecological procedures, by reducing length of stay and day morbidity.
Because of the need to attend to laryngectomyy problem, there will be limited time for radiological imaging.

Anaesthesia for patients with laryngeal cancer. Laryngectomy is performed in specialist centres and requires a team approach to airway management. Induction of anaesthesia If a patient is already at risk of airway obstruction due to tumour bulk, then it is probable that they will be at greater risk following induction of anaesthesia, whether intravenous or inhalational.
Neck haematoma, flap failures, fistulas and airway management issues e. Specific operative considerations The compromised airway In the patient who presents with acute airway compromise the obvious option is to consider a tracheostomy under local anaesthesia. Acute presentations with stridor require a collaborative approach to the airway that only rarely involves awake fibre-optic intubation.
Heliox mixtures may provide symptomatic relief, while further information is obtained, e. It is essential that anyone dealing with these situations must know what surgery has been performed and whether oral intubation is a feasible alternative. Care of the tracheostomy The Intensive Care Society has produced guidelines for the management of tracheostomy and temporary tracheostomy aaesthesia particular.
Dealing with any of these issues commonly requires senior and experienced staff and they laryngechomy frequently resort to conventional oral intubation to secure the airway prior to re-establishing the compromised tracheostomy, but oral intubation may not be feasible either because this is physically impossible e.
A surgical safety checklist to reduce morbidity and mortality in a global population. The Journal of Laryngology and Otology.
Anaesthesia for total laryngectomy.
Current practice has also been influenced by the introduction of many new intubation devices, very few of which have been reported in large series of head and neck cancer patients. These alternatives tend to become more of a problem if the operative procedure is prolonged.
Neck haematomas can be particularly deceptive because any associated airway oedema bears little resemblance to the apparent severity of neck swelling. Enhanced recovery in colorectal resections: Hypotensive conditions may minimise blood loss and haemodilution is practiced in some institutions with a view to improved blood flow in free flaps.
Tumour de-bulking to improve airway patency Whether or not the patient presents as an emergency, there are two objectives. Post-operative haemorrhage and oedema risks mean that tracheostomy remains an important consideration in extensive resections. Post laryngectomy patients can present for other types of surgery and a clear plan must be made for the management of such patients.
Abstract This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. Contractures resulting from the previous treatment are common in patients with head and neck cancer. This sort of haemorrhage can arise suddenly and with little warning.
Support Center Support Center. Relevant pre-operative measures might include carbohydrate loading with carbohydrate drinks 1—2 days before surgery. The risk of airway fires due to laser is low provided careful precautions including laser safe tubes are used.
Even local anaesthesia is not without risk because severe airway obstruction precipitated by laryngospasm has occurred.

These equate to the anaesthssia to protect from gravity-related anaesthexia effects, thermal homeostasis, retention of urine and prolonged wake up time.

Doppler probes are available to monitor anastomotic vessel patency but are expensive and tend to be restricted in use to inaccessible sites, composite flaps where skin colour may not reflect the deeper layer viabilitycontinued arterial spasm risk and patients who have had previous radiation.
If a patient is already at risk of airway obstruction due to tumour bulk, then it is probable that they will be at greater risk following induction of anaesthesia, whether intravenous or inhalational.
For lengthy operative procedures increased attention needs to be paid to the inevitable consequences of prolonged immobility, impaired homeostasis associated with general anaesthesia and the saturation of fatty tissue with anaesthetic agents. Ideally, any surgeon would wish to have an unrestricted view of the lesion to be operated on.
